DOUBLE-ACTION PUMP.

Specification of Letters Patent.

" Patented miga-1920.

Application-filed November 18, 1918. Serial No. 263,051.

To all whom it may concern.'

Be it known that we, VERLA L. FoRMwAY and SAMUEL S. SLONEKER, citizens of the United States, residing at Plainview, in the county of Hale, State of Texas, have 1nvented certain new and useful Improvements in Double-Action Pumps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in pumps and particularly to windmill pumps.

One object of the present invention 1s to provide a novel and improved double acting windmill pump. r

Another object of the present invention is to provide a novel and improved device for a windmill wherein the stroke of the pump rod causes the opening of one valve and the closing of the other.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a vertical longitudinal sectional view through the improved pump actuating mechanism and a portion of the well tube.

Fig. 2 is a horizontal sectional view takenV on the line 2 2 of Fig. 1.

Referring particularly to the accompanying drawing, 10 represents a portion of the well tube or casing in which are disposed the upper valve 11 and the lower valve 12, the former being connected to the outer rod 14 and the latter to the inner rod 13. As clearly seen in the drawing, these rods 13 and 14 are disposed in telescoping relation to each other. Mounted on the upper end of the casing 10 is a cylindrical housing 15,

into which the said rods extend, as clearly y seen in Fig. 1, the housing 15 having oppositely disposed side extensions as shown in Fig. 2. Vertically slidable in the casing 10 is a horizontally disposed disk 16, and through this disk the inner rod 13 extends, while the upper end of the outer rod 14 is secured to and moves vertically with the said disk. This disk16is provided with arms which extend into the side extensions of the housing 15 and carry racks 17 which extend upwardly through the side extensions of the housing. It will thus be seen that the disk will be prevented from turning, and the racks retained in the desired position. The

opposite faces of the portion of the inner rod 13, above said disk, are formed with the longitudinal series of teeth 18. Extending transversely of the casing, above the disk, and rotatably supported, at their ends, in

.the sidewalls of the casing, are the horizontal parallel shafts 19, on each of which is mounted a pinion 20. These pinions, as clearly seen in Fig. 1, are disposed on opposite sides of the rod 13, and each meshes with one set of teeth of said rod, and with the teeth of one of the rack bars 17. Thus when the rod`l3 moves upwardly the pinions 20. will be rotated with the result that, by reason of their meshing engagement with the rack bars 17, the disk, and with it, rod 14, will move downwardly. This will result in the closing of the upper valve 11 and the opening of the lower valve 12. A reverse movement of the rods will cause the upper valve to open and the lower valve to close. Thus at each stroke of the pump rod there will be a double action of the pump.

rod 14, to prevent leakage therebetween. A slmilar nut 22 is disposed around the rod 13, and in the upper side of the disk.

What is claimed is:

In a device of the character described, a well tube, a tubular housing carried by the well tube, the housing having vertically extending side extensions, upper and lower valves slidablymounted in the well tube, a disk slidably mounted in the housing and havin side arms extending into the side extensions of the housing to retain the disk against rotary movement, rack bars extending from the arms of the disk through the side extensions of the housing, a hollow rod extending from the disk 'into the well tube and engaging the upper valve, a pump rod extending from the lower valve through the VERLA L. FORMWAY. SAMUEL S. SLONEKER.
